Was Harriet Beecher Stowe a Confederate?

Answer 1

Harriet Beecher Stowe was not affiliated with the Confederate movement.

When Congress had to appease the South in order to get California admitted as free soil, they promised to appoint official slave-catchers to hunt down runaways and return them to their owners.

This caused Harriet Beecher Stowe who promptly write 'Uncle Tom's Cabin'

Second idea: Harriet Beecher Stowe had been an avid abolitionist before California became a state. There is no evidence that statehood for California in 1850 is related to Ms. Stowe's motives for writing Uncle Tom's Cabin. It was Harriet Beecher Stowe's sister in law who told her about the Fugitive Slave Act and that perhaps Harriet should use her writing skills to help end slavery.
